Abstract (en)
[origin: WO9323720A1] The present invention relates to a position sensor of the type comprising a stator presenting a slot forming an air-gap inside which is positioned a permanent magnet, and comprising means for measuring the magnetic flow consisting of a magnetism-sensitive probe (7). The magnet (3) is of the bipolar type and is movable inside a main thin air-gap (2) delimited by the ferromagnetic parts (4, 5) joined by non-magnetic connecting parts (10, 11). The length of the air-gap (2) measured along the direction of displacement of the movable magnet (3) is at least 2 (C + E), C designating the travel of the magnet (3) and E designating the width of the air-gap (2), the length of the magnet (3) being at least equal to (C + E) and its travel being at least C/2 with respect to the secondary air-gap (6, 73) perpendicular to the main air-gap (2).
